" 1 SASH-LOCK.

Application filed May 15,

- raised more or less for ventilating purposes.

The sash lock also prevents the lower sash from being opened.

' In the accompanying drawings, Figure 1 is a front view of my improved sash-lock, showing it applied to a window-frame: Fig. 2 is a section on line 2 '2,Fig. 1; and Fig.3, a perspective view of the sash-lock.

A base-plate 4 is adapted to be attached to awindow-frame 5 so as to project above the top rail 6 of the lower sash 7 when the latter is lowered. To plate 4 is pivoted at 8 a twoarm lever 9, the rear arm of which has a handle 10. To the front arm of the lever is pivoted at 11 a dog 12, the eccentrically-curved working edge of which is cushioned, as at 13.

A spring 14, attached by stud 15 to lever 9 and engaging the tail of dog 12, tends to swing the latter downward. The rear arm of lever9 is adapted to be engaged by a catch 16, pivoted to'plate 4 at 17 and weighted, as

In use lever 9 is swung horizontally across 16 is swung upward to engage said lever, and

are so proportioned and assembled that the edge 13 the inner side of upper sash 19, the dog being tilted slightly upward while the spring 14 is compressed. It will be seen that the dog will be so jammed against upper sash 19 that the latter cannot be lowered, but that lower sash 7 is by lever 9 locked againstany movement. v

If -it'is desired to release the sashes, the catch 16 is thrown out of engagement with lever 9, and the latter is swung upward by handle 10, carrying dog 12 with it.

What I claim is A sash-lock provided with a base-plate, a

two-arm lever pivoted thereto, a spring-inlever-arm, and a catch pivoted to the plate and adapted to engage the rear lever-arm, substantially as specified.
